Hello I came across your message the other day, and found it of interest. Several years ago one of my wifes uncles found the following and passed it on, "17th March 1932 EMPSON @ Mercedes in Uruguay to the wife of Christopher Empson a son ( by cable)". A few days later we visited Blacktoft Church near Yokefleet and by chance found the following in the visitors book, "27/6/63 Evelyn Empson Montevideo, Republic of Uruguay". I often thought that this Christopher was one I had found in the records of York Library who seemed to disappear. Thanks to your reply to Richard I know that not to be the case.
Fascinating how far the Empson name has spread over the years.
